EYELETING-MACHINE AND THE LIKE.

To all whom t may concern Be it known that I, SYLVESTER L. GooKIN, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Eyeleting-Machines and the like, of which the following description, 1n connection with the accompanying drawings, is a specification, like'reference characters on the drawings indicating like parts in the several figures.

This invention relates to improvements in machines for setting eyelets or other tubular fasteners and more particularly to upsetting tools for such machines.

Blind or invisible eyelets are set in one part of a shoe upper in register with a hole punched in the other part for the passage of the' lacing. Eyelets set in the lining beneath a hole in the outer part of the upper are designated as invisible eyelets, and eyelets set in the outer part of the upper above a hole in the lining are designated as blind eyelets. The eyelets of both classes may be set by substantially the same tools, the only difference being in the manner of presenting the work to the machine.

There is more or less variation vin the thickness of the different layers of sheet material which make up the various shoe uppers to be eyeleted in a shoe factory. The conditions also are frequently varied by the introduction or the omission of one or more layers of textile material for stiffening.

An object of the present invention is to provide an upsetting tool which may be used successfully for setting blind or invisible eyelets in shoe parts of varying thickness. This, it is believed, has never before been attempted.

In accordance with one feature of the l present invention the pilot and upsetting surface of the upsetting tool are made relatively adjustable and the tool is arranged to enter the shoe upper as it rests upon a support. By adjusting the upsetting surface nearer to or fartherfrom the end of the pilot the upsetting surface may be made to pass varying distances into the upper so that when an eyelet is subsequently inserted from the other side of the upper its end will be clenched at the proper place. For example, if invisible eyelets are to be set in a lining of unusual thickness or a lining reinforced with a thick stiening strip the Specification of Letters Pateit.

upsetting surface will be adjusted to a point vfarther above the end of the'pilot than would be the case in setting an invisible eyelet in a thin lining.

Another important feature of the invention consists in the provision of an upsetting tool of which the upsetting surface and pilot are relatively adjustable so that in one position of relative adjustment blind or invisible eyelets may be set, and in another position of relative adjustment eyelets may be set in the usual manner, that is, with their flanges on one side of the work and their barrels passing entirely through all portions of the work and being clenched upon the opposite side. In accordancewith the p `esent invention this is effected by adjusting the upsetting surface sufficiently above the end of the pilot to insure that the upsetting surface shall not enter the Work but permit vthe eyelet barrel to pass entirely through it before the clenching operation takes place. This feature of the invention is of importance because it enables the operatorto use the same machine, fitted with the same tools, for blind work or for regular Work, and in practice the requirements may change with every case of shoesthat comes to the operator. As herein shown. though not necessarily, the pilot is utilized as a punch and such construction constitutes another important feature of the invention. The cutting bed valso may, to good advantage, be utilized as the work support in which case the upsetting surface Will be forced into the upper to the proper point during the punching operation. This arrangement is advantageous in that it insures great uniformity of operation. and consequently work of good quality.

The invention is described as an improvement in eyeleting machines and its most useful application is in this field although it is contemplated that the upsetting tool herein disclosed may be utilized for inserting lacing hooks if so desired.

The features above discussed and others will be best understood and appreciated from the following description ofa preferred embodiment of the invention selected for purposes of illustration and shown in the ac 3o f the feeding steps.

perspective on an enlarged scale of the upsetting tool; Fig. 3 is a sectional view showing the parts of the machine in the position which they occupy at the conclusion of the punching operation; Fig. 4 is a similar view showing the parts of the machine in the position which they occupy at the conclusion of the setting operation, and Fig. 5 is a similar ing set 8 is adjustably mounted in the plunger 6 and is provided with the usual center spindle' 10. Eyelets are supplied to the set 8 during its upward movement by a raceway not shown. A work table 4 is secured to the frame and is perforated to permit the passage of the lower set 8. A presser foot 12 serves to clamp the work in place upon the table 4 during the intermissions between A At the rear of the work table there is mounted a lever. 14 which carries the upsetting tool and is given, in addition to its vertical movement, a transverse movement to feed the work. The work table:

4 is slotted to receive a hardened cutting block 16 which acts also as a work support during the punching operation.

The upsetting tool, of which the punch forms a part, consists of a cylindrical shank portion 20, a reduced threaded portion 22, a punch 24 of smaller diameter, and a sleeve 26 upon which is formed the upsetting surface 28. The punch 24 is tubular and communicates with a passage extending upwardly through the body portion of the tool so that the punchings may be ejected through its upper end. The sleeve 26 is internally threaded and fitted upon the portion 22 of the tool. It has an enlarged and knurled body portion by which it may be gripped and turned by the operator while at its lower end it is taperedrinwardly to form a cylindrical collar 32 of relatively small diameter. The upsettingsurface is formed on the lower edge of this collar and practically merges into the outer cylindrical surface of the punch 24 which thus constitutes the pilot of the upsetting die.

` The combined upsetting and punching tool is adjustably mounted in the forward end of the lever 14, being backed up by an adjustable bearing piece 40 which is threaded into the lever 14 and provided with a lock nut 42. A set screw 44 is provided for retaining the tool in place while its position in the lever is determined by the setting of the bearing piece 40.

It will be apparent that by turning the sleeve 26 upon the threaded portion 22 of the tool the upsetting die surface 28 will be carried nearer to or farther from the end of the punch 24. As this part of the punch is forced completely through the work in the punching operation the depth to which the upsetting surface will be forced into the work may be accurately determined by the setting of the sleeve 26.

In Fig. 3 the machine is illustrated as adjusted for inserting blind or invisible eyelets in the lining 54 and stiffening strip 52 of an upper beneath the hole for the lacing formed in the outer part 50. As shown in' this figure the end of the punch is forced through the work into engagement with the surface of the cutting block 16 and the upsetting die surface has been crowded into the hole in the outer part 5() of the upper and carried approximately through this part of the work. In the operation of the machine the tool is then lifted just sufficiently to clear the surface of the cutting block and moved toward the left feeding the work with it until .it comes into vertical alinement with the lower set 8. The latter is then elevated and an eyelet forced into the upper until the end of its barrel encounters the upsetting surface by which it is clenched.- This condition of affairs is illustrated in Fig. 4.

The position of the upsetting surface 28 in the work may be adjusted with eXtreme accuracy and the clenched end of the barrel accordingly may be brought wherever desired. With the tool as adjusted in Fig. 3 the eyelet barrel passes. through two thicknesses, the liningv 54 and the stiffening strip 52, before its end is clenched, but by slightly lowering the sleeve 26 the upsetting surface may be made to enter the stiffening strip 52 so that the eyelet will be clenched upon the vsurface of the lining 54' and independently of the stiffening strip`52 if this were to be desired. On the other hand the sleeve 26 may be moved upwardly and the upsetting surface 28 located at a greater distance from the end of the punch 24. Such an adjustment is illustrated in Fig. 5 where the sleeve 26 is shown as elevated suiiiciently to permit the eyelet barrel to pass through all parts of the work and to be clenched upon 'l its outer surface. With the tool so adjusted therefore, eyelets may .be set in the usual manner.

It will be seen that the different adjustments provided for in the above described tool permit all parts of the machine to be positioned to the best advantage with respect to their coperating parts. The bodily adjustment of thetool afforded by the bearing piece 20 permits thev precise adjustment of the punch with respect to the Cutting block 16 which is essential for properly perforating the work. The adjustment of the sleeve Q6 upon the tool permits the proper location of the upsetting surface without in any way disturbing the previously adjusted relation of the punch and cutting block.
